    Ensure network connectivity for linuxbridge flat network.

    Fixes bug 1040447

    In the event that an IP address and gateway are defined on an interface that is
    used in a flat network, then the interface details will be copied to the
    bridge when it is created.
    If the network is deleted then the IP addresses are returned to the interface.
